Abstract

Antibacterial activity of Moringa oleifera Lam. stem bark has been tested against Staphylococcus aureus and Escherichia coli. The extraction of Moringa oleifera Lam. stem bark was used maceration method with methanol solvent and has obtained extract yield of 6.1%. The antibacterial activity test of Moringa oleifera stem bark extracts used a well diffusion method. The concentration of Moringa oleifera stem bark extract was varied to four concentrations of 1% 2% 3% 4% (w/v). The inhibition zone of methanol extract of Moringa oleifera stem bark against Staphylococcus aureus at extract concentrations of 1%, 2%, 3%, and 4% was 10.08 mm, 11.8 mm, 15.00 mm, and 17.02 mm, respectively. The methanol extract of Moringa oleifera stem bark at concentrations of 1%, 2%, 3%, and 4% could also inhibition of Escherichia coli growth with inhibition zone of 14.01 mm, 16.50 mm, 17.09 mm, and 17.10 mm, respectively. Keywords: Moringa Oleifera Lam., Antibacterial, Staphylococcus aureus, Escherichia coli

Sapir in Lyons (1982: 3) says that language is used by humans to communicate, express emotions and desires through various symbols. While Wardhaugh added that language is an arbitrary system which basically has a function as a tool for communicating. This study aims to determine code mixing in the novel language. This type of research method used is qualitative research. The method used is descriptive method, which is a research method that describes data starting from the data collection stage, data compilation, accompanied by data analysis and interpretation. In this study, the type of data analyzed using written data. The data source in this study is a novel entitled Negeri Lima Menara by A. Fuadi. Data was collected by examining data from data sources using the basic method of observation, namely by observing the form of code mixing contained in the novel in the form of sentences and followed by the method of recording data from previously observed data. Then the researcher analyzes the form of code mixing contained in the novel and concludes the results obtained. Based on the results of the analysis of the collected data, it was concluded that the incident of mixing the Minang language code into Indonesian, Javanese into Surabaya dialect into Indonesian, Sundanese into Indonesian, Arabic into Indonesian, and English into Indonesian. The sociolinguistic meaning contained in the Negeri Lima Menara novel is the meaning of intimacy and is related to kinship culture in communicating in a multilingual society which is often used in communicating within family, friends, and Islamic boarding schools.

Abstract

Reading skills in the early grades play an important role as the basis or foundation for successful academic activities. However, there are still many students who need help learning to read. The research to analyzing the difficulties of beginning reading. To describe the factors that cause learning difficulties in beginning reading. To explain solutions that can be used in overcoming learning difficulties in beginning reading. This research uses qualitative research methods with phenomenological design. The place and time of the research was Tungalsari II State Elementary School, Surakarta Indonesia. The subjects of this research were teachers, guardians, and second-grade students. A credibility test was used to test the validity of the data obtained. Data collection techniques through observation, interviews, and documentation. Data analysis technique with flow method. The results showed that students' difficulties in beginning reading are recognizing letters, not being able to string syllables, and so on. Factors that influence learning difficulties in beginning reading, namely: lack of student interest in learning, lack of parental attention, and so on. Alternative solutions to early reading difficulties include; teachers holding additional hours for students who still have difficulty learning to read, teachers paying special attention to students who have difficulty reading, and so on. In this research reveals the factors and alternative solutions used by teachers in overcoming elementary school students' reading learning difficulties.

Abstract

The role of women is not only to be a wife and housewife, but their existence can provide its color in economic activities. This research aims to analyze of determinants influencing the labor force participation rate of women in East Java Province for the years 2018-2022. This research consisted of 38 regencies/cities in East Java Province over 5 years so there were 190 observations, obtained from the Central Statistics Agency (BPS). This research method uses quantitative analysis with panel data regression. The research results show that the best model is the Fixed Effect Model. Partially, women's per capita expenditure (X1) has a positive and insignificant effect on the labor force participation rate of women (Y). The average number of years of schooling for women (X2) has a positive and significant effect on the labor force participation rate of women (Y). The minimum wage in districts/cities (X3) has a negative and insignificant effect on the labor force participation rate of women (Y). Gross Regional Domestic Product (X4) has a negative and significant effect on the labor force participation rate of women (Y). Simultaneous research results in women's per capita expenditure (X1), average years of schooling for women (X2), minimum wage in districts/cities (X3), and Gross Regional Domestic Product (X4) together have a significant effect on the labor force participation rate of women (Y). As the number of labor force participation rate of women increases every year, it is hoped that the development strategy in East Java District/City will move towards a strategy that prioritizes improving the quality of human resources, through soft skills and hard skills training.
